In this second part of a two-part study, we performed a simulation of the carbon and water budget of the Lena catchment with the land surface model ORCHIDEE MICT-LEAK, enabled to simulate dissolved organic carbon (DOC) production in soils and its tra

ORCHIDEE MICT-LEAK (r5459), a global model for the production, transport, and transformation of dissolved organic carbon from Arctic permafrost regions – Part 1: Rationale, model description, and simulation protocol

Autor: S. P. K. Bowring, R. Lauerwald, B. Guenet, D. Zhu, M. Guimberteau, A. Tootchi, A. Ducharne, P. Ciais

Publikováno v: Geoscientific Model Development, Vol 12, Pp 3503-3521 (2019)

Few Earth system models adequately represent the unique permafrost soil biogeochemistry and its respective processes; this significantly contributes to uncertainty in estimating their responses, and that of the planet at large, to warming. Likewise,

Modelling northern peatland area and carbon dynamics since the Holocene with the ORCHIDEE-PEAT land surface model (SVN r5488)

Autor: C. Qiu, D. Zhu, P. Ciais, B. Guenet, S. Peng, G. Krinner, A. Tootchi, A. Ducharne, A. Hastie

Publikováno v: Geoscientific Model Development, Vol 12, Pp 2961-2982 (2019)

The importance of northern peatlands in the global carbon cycle has been recognized, especially for long-term changes. Yet, the complex interactions between climate and peatland hydrology, carbon storage, and area dynamics make it challenging to repr

Multi-source global wetland maps combining surface water imagery and groundwater constraints

Autor: A. Tootchi, A. Jost, A. Ducharne

Publikováno v: Earth System Science Data, Vol 11, Pp 189-220 (2019)

Many maps of open water and wetlands have been developed based on three main methods: (i) compiling national and regional wetland surveys, (ii) identifying inundated areas via satellite imagery and (iii) delineating wetlands as shallow water table ar

A critical appraisal of water table depth estimation: Challenges and opportunities within machine learning

Autor: Janssen, Joseph, Tootchi, Ardalan, Ameli, Ali A.

Fine-resolution spatial patterns of water table depth (WTD) play a crucial role in shaping ecological resilience, hydrological connectivity, and anthropocentric objectives. Generally, a large-scale (e.g., continental or global) spatial map of static
